Monday, May 4, 2026, New Orleans woke to clear skies and cool, comfortable air, with KNEW reporting about 61°F early this morning. Sunshine is expected to hang around through the afternoon and nudge highs into the upper 70s, a sweet setup for errands, outdoor lunch, or a quick walk along the lakefront before work. The quiet stretch will be short-lived, though, with a frontal system lined up for midweek that should flip the switch to a wetter, occasionally stormy pattern later in the week.
Afternoon and Tonight
Forecasters are calling for sun and a high near 79°F this afternoon, with temperatures easing back into the upper 70s by late day and south winds around 0 to 10 mph. Tonight stays mostly clear with a low near 63°F and a light south breeze. According to the National Weather Service, this is essentially a brief quiet window before a stronger system starts to move in around midweek.
Wednesday Into The Weekend
The next shot at strong to severe storms arrives Wednesday night, when a front could spark thunderstorms and heavy downpours. Additional rounds of rain are likely from Thursday through Saturday. Some storms may produce heavy rainfall and localized street flooding, especially if multiple cells track over the same neighborhoods.

Impacts And Advice
Plan for soggy commutes later in the week, with standing water on low-lying streets and reduced visibility in heavier downpours the main near-term concerns. Boaters and anyone with plans on Lake Pontchartrain should be ready for increasing winds by midweek and the possibility of Small Craft Advisories. Keep weather alerts on, give yourself extra travel time when the rain moves in, and avoid driving through flooded roads. Local advisories will be key as the week unfolds.
Quick Take
Today: sunny and pleasant, high near 79°F. Midweek: watch Wednesday night through Friday for the greatest storm and heavy-rain chances.
